Two wavelengths of light are incident simultaneously on a transmission grating which has 3000 lines per cm. The fifth order image due to one wavelength occurs at the same place as the sixth order image of the other in the diffraction pattern. If one of the wavelength is longer than the other by 0.11 x 10-6 m, calculate: the values of the wavelengths the Angular displacement away from the center of the diffraction at which the coincidence occurs.
